TOBACCO-PIPE.

SPECIFICATION forming part of Letters Patent No. 379,585, dated March20, 1888.

Application tiled September 3, 1887.

To aZZ wit/077'. it may concern.-

Beit-known that I, J OHN F. MALLINcKRon'r, of Denver, in the county ofArapahoe and State of Colorado, have invented certain new and usefulImprovements in Tobacco-Pipes; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appcrtains to make and usethe same.

My invention relates to an improvement in pipes for smokers use.

The object of my invention is to produce a tobacco-pipe that will, fromits method of construction and materials employed in its manu facture,afford a means for the ready removal and renewal of parts that areliable to become impregnated with nicotine, so that a practically newpipe may thus be afforded at a trifling cost to the user.

A further object is to provide a tobacco-pipe with an absorbent liningthroughout its bowl and stem, which is adapted to be removed when itbecomes foul and a similar new lining introduced in place of the porouslining that has become saturated with nicotine, the stem locking theinserted bowl when both are in place for use.

A further object is to construct a tobaccopipe having its stem composedofa perforated outer shell and a porous inner tubular lining, so thatthe latter will absorb the essential-oil of the consumed tobacco andallow it to escape by evaporation through the perforated outer shell ofthe pipe stem.

Vith these objects in view my invention consists in certain features ofconstruction, novel combinations of parts, and the employment of aporous material, as will be hereinafter described and pointed out in theclaims.

Referring to the drawing, which is represented in one figure, the bowland lining are shown in sectional elevation and the stem partly inperspective, its end that is inserted into the bowl and the tip ormouth-piece being shown in section to expose interior constructivefeatures.

A is the outer bowl of the pipe, made of any preferred suitablesubstance and pressed or molded into form, or may be carved into shapeif wood is utilized as a material for its manu- Serinl No. 248,722. (Nomodel.)

facture. The hollow chamber of the bowl A is somewhat larger in diameterat the upper end, this cavity being tapered conically, as shown.

The shell B is made to fit into the cavity of the bowl A, and has aconical nipple, a, formed on one side at its lower end. The nipple adoes not project outward beyond the outer surface of the inclined wallof the shell B; hence it will offer no impediment to the free inscrtionof said shell into place in the cavityprovided for its reception in thebowl of the pipe. A proper-sized perforation, c, is made in the vertexof the cone 0, which extends centrally through the cone till thehollowspace or chamber of the shell B is intersected by it at the point ((3.

Upon the bowl A the usual integral branchpiece, A, is formed for theattachment of the stem to the bowl.

The shell B is composed of any suitable absorbent material; butpreference is given to paper-pulp molded into form and dried to producea substantial wall or shell, its porous nature rendering it capable oftaking up by capillary action the nicotine resulting from the burning ofthe tobacco in it.

The branch piece A of the bowl A has an axial perforation that is ofproper diameter to receive the stem of the pipe. This stem is composedof an outer metallic tube, 0, which is numerously perforated at spacedintervals throughout its surface.

The met-a1 tube (3 is provided with a removable porous sleevc, D, havinga longitudinal orifice extending through it for the passage of smokefrom'the tobacco contained in shell B when the pipe is in use.

A tip or mouthpiece, E, is recessed at one end to receive the freeextremity of the pipestem 0 D, and a conical joint, I), is made integralwith the material of the mouth-piece E, the usual small smoke-passageaxially perforating the mouthpiece and conical joint made in it.

The metallic stem C and its porous liningsleeve D are cut squarely offat each end, and the longitudinal hole through the sleeve is of sucharelative size tothe conical joints a b that when the stem is forcedinto the branch A of the pipe-bowl A and the mouth-piece E similarlyconnected to the stem 0 D a continuous air'passage will be afforded andno leakage of air will be permitted at the points of attachment justnamed.

In operation, the pipe being connected as shown, the act of smokingignited tobacco placed in the shell B will discharge smokethroughthesmallorificea intothe larger bore of the porous sleeve D ofthe stem, and the smoke will move comparatively slowly through the stemand deposit the nicotine it is pervaded with on the absorbent sleeve D,which acts as a sponge and becomes saturated with this essential-oilvapor, the heat of the pipe driving it to the outer surface of theporous shelland causing considerable of its volume to pass off throughthe perforations e of the metallic tubular stem 0. WVhen the shell Bandstem 0 D are conneeted,as sh own in the figure, the yielding nature ofthe porous sleeve D will allow its engaged end to be slightly compressedby the cone-joint a, and the metal tube portion 0 of the stem willproject over the body of the cone a in a manner to hold the shell Blocked fast in its seat, and thus render it a stable fixture with regardto location in the bowl A. It is apparent that a removal of the stem 0 Dwill release the shell B, and it may then be dislodged by a slight tapof the bowl A upon any rigid substance.

The porous sleeve D may be easily pushed out of the metal stem 0 andboth the shell and sleeve be renewed as frequently as may be desired,thus providing a new absorbent surface, and in effect a new pipe.

When proper provision for extensive manufacture is made, the absorbentportions of my improved pipe may be made cheaply and atforded forgeneral use at alow cost to the consumer, so that a cheap, compact, neatpipe, devoid of objectionable features incident to ordinary pipes, isthus afforded.

Having fully described my invention,what I claim as new, and desire tosecure by Letters Patent, is-

1. In a tobacco-pipe, the combination, with a bowl and an innerremovable shell, ofastem passing through the bowl and attachedlto anipple or projection on the shell.

2. The combination,with amouth-piece and a bowl provided with ashell,the latter having a perforated nipple, of a stem one end of which passesthrough the bowl and engages the nipple or projection on the shell, anda mouth-piece having a recess for the reception of the other end of thestem, substantially as set forth.

3. In a tobacco pipe, the combination, with a bowl having a conicalchamber, of a porous shell made to fit the conical chamber of the bowl,and provided with a cone-joint at one side of its lower end, which isperforated to furnishasmoke-passage from the cavity of the shell,substantially as set forth.

4. In a tobacco-pipe, the combination, with a tubular metallic stem andan internal porous lining, of a longitudinally perforated mouth-piecehaving a conical projection made integral with the body of thismouth-piece, and adapted to enter said lining and lock the mouth-piecethereto and also lock the lining within the stem, substantially as setforth.

. 5. In atobacco'pipe, the combination, with a pipe-bowl, a porousshell, and an integral perforated nipple that projects from one side ofthe shell, of a foraminated tubular stem having a porous lining, and amouth-piece provided with a cone-seat, both cone-seats being adapted toengage the ends of the porous lining to render the pipestem air-tight atits points of connection with the shell and mouthpiece, substantially asset forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
